The package also comes with flags to enable six different backends.
The native SVG backend is
enabled by the -fsvg flag and is enabled by default. If you don't
want it, you must explicitly disable it with -f-svg.

The cairo backend is
disabled by default but can be selected with the -fcairo flag. In
addition, the GTK backend
is based on the cairo backend (but split into a separate package to
make installing the cairo backend easier). It can be selected with
the fgtk flag.
